Properties Manager

Can someone tell if you know some framework to manage the application properties of a company? We want tha all the configuration information (Properties) of all of our application be in a common repository and we want to administrate them with a common interface. For example: We have 4 web applications and many EJBs, and we do no like to be editing web.xml files, or properties files, or ejb-jar.xml files.

If the properties are stored in the DB, then a simple interface could be about providing a simple list-all properties page (JSP page/ something) with ability to change the property values and save them to the DB?
